BR-X1 TOURBILLON SKELETON SAPPHIRE BLACK BRX1-SKTB-SABLK

Beyond the watchmaking performance, it is the use of sapphire that gives the BR-X1 SKELETON TOURBILLON SAPPHIRE all its rarity and beauty. The sapphire case is a bit like an X-ray that allows you to visualize the structure of the case to better understand its assembly, while allowing the eye to freely dive into the heart of the watch and its movement. By exposing the soul of a one-of-a-kind watch to the viewer, the spectacle becomes magical.
